Description

Technical Field

[0001] The utility model relates to the technical field of shoes, in particular to a mid-high heel sole connection buffer structure. Background Art

[0002] At present, most of the mid-heeled shoe soles available on the market are made by mold injection molding. The material of this type of sole is usually softer materials such as foam materials or rubber. However, after the sole is made, it is still necessary to connect the midsole. After the midsole and the sole are bonded by brushing glue, they also need to be connected and fixed to the heel of the sole by screws to make the connection between the midsole and the sole more firm and stable. However, the sole made of softer materials cannot give the screws enough adhesion, thereby causing the screws to lose their tightening function. On the other hand, the softer sole cannot provide enough support for the wearer, making it easy for the wearer to sprain his ankle when walking, reducing comfort. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a mid-high heel sole connection buffer structure that can more firmly and stably connect the sole and the midsole and increase the supporting force of the heel.

[0004] To this end, the utility model is implemented by adopting the following technical solutions:

[0005] The mid-high heel sole connection buffer structure comprises a sole, wherein the heel portion of the sole has a hollow portion and a connection portion, and is characterized in that: the connection portion is embedded with a connection column, and the connection column is used for connection and fixation with the midsole.

[0006] Furthermore, the hardness of the connecting column is greater than the hardness of the sole.

[0007] Furthermore, the connecting column is provided with a connecting hole.

[0008] Furthermore, the connecting column includes an upper column and a lower column, the upper end of the lower column is provided with a sleeve, the lower end of the upper column is inserted into the sleeve, a damper is provided in the lower column, the damper includes an outer shell and a piston rod passing through the outer shell, the outer shell has a buffer, the upper end of the piston rod is connected to the bottom of the upper column, and the lower end is connected to a working piston.

[0009] Furthermore, a floating piston is provided in the shell, the floating piston is located at the lower part of the shell, and a plurality of sealing rings are provided on the outer ring of the floating piston. The buffer solution is filled in the shell above the floating piston, and the shell below the floating piston has buffer gas.

[0010] Furthermore, a flat plate is provided at the upper end of the piston rod, and the flat plate is bonded to the bottom surface of the upper cylinder by glue.

[0011] After adopting the above technical solution, a connecting column is embedded in the connecting part of the heel of the sole for fixing with the midsole. The connecting column is made of a material with a harder hardness than the sole, so that the screw has sufficient adhesion after being screwed in, thereby making the midsole and the sole more firmly and stably connected. At the same time, the connecting column increases the supporting force of the heel, avoids the wearer's ankle from spraining when walking, and enhances wearing comfort.

DETAILED DESCRIPTION

[0016] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0017] Referring to the above-mentioned drawings, the mid-high heel sole connection buffer structure provided by the utility model includes a sole 1, the heel portion of the sole 1 has a hollow portion 2 and a connection portion 3, and is characterized in that: the connection portion 3 is embedded with a connection column 4, the connection column 4 is used to connect and fix with the midsole, the hardness of the connection column 4 is greater than the hardness of the sole 1, and the connection column 4 is provided with a connection hole 5.

[0018] In this embodiment, a connecting column 4 is embedded in the connecting portion 3 of the heel of the sole 1 for fixing to the midsole. The connecting column 4 is made of a material with a harderness than that of the sole 1, so that the screw has sufficient adhesion after being screwed in, thereby making the midsole and the sole 1 more firmly and stably connected. At the same time, the connecting column 4 increases the supporting force of the heel, avoiding the wearer's ankle sprain when walking, and enhancing the wearing comfort. In addition, the setting of the connecting hole 5 facilitates the installation of the screw, and the combination with the screw is more stable and firm. If there is no hole, the screw screwing in may easily cause the connecting column 4 to burst.

[0019] Reference Figure 2As shown, the connecting column 4 includes an upper column 6 and a lower column 7. The upper end of the lower column 7 is provided with a sleeve 8, and the lower end of the upper column 6 is inserted into the sleeve 8. A damper is provided in the lower column 7. The damper includes an outer shell 9 and a piston rod 10 inserted through the outer shell 9. A buffer 11 is provided in the outer shell 9. The upper end of the piston rod 10 is connected to the bottom of the upper column 6, and the lower end is connected to a working piston 12. A floating piston 13 is also provided in the outer shell 9. The floating piston 13 is located at the lower part of the outer shell 9. A plurality of sealing rings 14 are provided on the outer ring of the floating piston 13. The buffer 11 is filled in the outer shell 9 above the floating piston 13. A buffer gas 15 is provided in the outer shell 9 below the floating piston 13. A flat plate 16 is provided at the upper end of the piston rod 10, and the flat plate 16 is bonded to the bottom surface of the upper column 6 by glue.

[0020] In this embodiment, the connecting column 4 is composed of an upper column 6 and a lower column 7, which are connected by a damper. The damper has a working piston 12 and a floating piston 13, and cooperates with a buffer solution 11 and a buffer gas 15 to give the piston rod 10 and the upper column 6 a good buffering effect to alleviate the damage to the heels of women during long-term walking. The floating piston 13 has multiple rings of sealing rings 14 to enhance its sealing and avoid mixing of the buffer solution 11 and the buffer gas 15. The setting of the flat plate 16 makes the connection between the piston rod 10 and the upper column 6 more stable and firm.

[0021] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
